Yes, indeed. https://reviews.llvm.org/D64537 gives a good 
overview.

I believe it is best to first actually have a version of druntime 
on wasm, rather than eagerly pulling in all the latest features. 
I find the scope I set in the proposal to be quite reasonable.

Adding tls, threading and exception handling would be much easier 
after this work is done and merged. And it would also be 
something others might want to contribute to.
